Abstract

Method for manufacturing panels, wherein the method at least comprises: - the step of providing semi-finished panels (1A) with at least a substrate (15) and a decorative top layer (18); - the step (S1) of performing a milling, sawing or scraping operation by means of one or several cutting tools (9) on at least one edge (3-4-5-6) of said semi-finished panels (1A), wherein the semi-finished panels (1A) are moved past said cutting tools (9) via a belt, air or chain conveyor (10) in a processing machine (7A-7B), and their decorative top layers (18) are moved across a sliding shoe (14) at the location of at least one of the cutting tools (9), and / or their sides which are turned away from the decorative top layer are moved past a pressure shoe (13); characterized in that the semi-finished panels (1A) are provided with a lubricant (22) on the decorative top layer (18) and / or on the side which is turned away from the decorative top layer (18) before or during said step (S1) of performing a milling, sawing or scraping operation.
